Aha ! I knew it would end up being something straightforward. I'll give it a whirl.

BTW - was laziness on my part to describe as a "download blocking tool" - but basically I meant that when I tried to download a file, an extra line would appear below the header line (again not sure what the exact terminology is for this, I'm referring to the very top blue line that makes up the I/E window, with the minimize / close buttons on), stating somthing along the lines of

"Internet Explorer has blocked a download. For options click here"

But of course by that time it would already be too late as the site had kicked me out !!!

But thanks very much for the help, is much appreciated
